Sandwich panel and method of making the same

Abstract

The invention discloses a sandwich panel, which comprises a bottom substrate, a plurality of metal wires, a plurality of spacer pads, a top substrate and a notch, wherein the metal wires are arranged on the bottom substrate and are arranged in parallel; the plurality of spacer pads are arranged on the bottom substrate; the spacer pads are separated from the metal wires; the thickness of each spacer pad is greater than that of each metal wire; the top substrate is laminated on the bottom substrate; when the top substrate is laminated on the bottom substrate, the top substrate is separated from the metal wires on the bottom substrate thorough the spacer pads; the notch is formed in one side edge of the top substrate; and at least partial metal wires and spacer pads are exposed from the notch. The invention further discloses a manufacturing method of the sandwich panel. According to the sandwich panel, the risk of damaging the metal wires in a panel cutting process is effectively reduced; exposing of the metal wires is avoided; the metal wires are not easily corroded; a reliability test is relatively easy to pass; and the yield of a product is greatly improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to a panel cutting process, in particular to a sandwich panel and a manufacturing method thereof, which can effectively reduce the damage of metal wires in the panel cutting process. Background technique [0002] At present, the panel is easy to cause damage to the metal wire during the cutting process, but the slight damage is difficult to detect during the lighting test, which will cause the subsequent reliability test to fail. If the metal wire damage cannot be effectively prevented, the reliability of the panel is difficult to obtain an effective measure. promote. The panel cutting process generally includes two aspects, one is the cutting process, and the other is the process of stripping off residual materials. Such as figure 1 and figure 2 As shown, 4 is the damage position of the metal wire. In the current process of cutting the panel, when the cuttin...
